The 66 pages that link to Redshift, each with the reason it gives.

• Markarian 501Related: Its small redshift is one measure of Markarian 501’s relative proximity.

• NGC 6946Related: Spectral shifts help measure NGC 6946’s motion and distinguish it from foreground stars.

• Observational cosmologyRelated: Galaxy redshifts provide a primary measure of cosmic expansion.

• BL LacertaeRelated: Its uncertain and disputed redshift has complicated estimates of the source's distance.

• Infrared telescopeRelated: Cosmic expansion shifts distant galaxies' ultraviolet and visible light into infrared bands.

• List of the most distant astronomical objectsRelated: Cosmological redshift is the principal observable used to compare many remote galaxies.

• SN 1972ERelated: Galaxy redshifts paired with supernova distances reveal the relation between recession and distance.

• South Pole WallRelated: Galaxy redshifts help estimate distances and map the wall’s extent.

• Timeline of cosmological theoriesRelated: Galaxy redshifts became a central observational clue to cosmic expansion.
